SPATIAL ASPECTS OF TRAFFIC CIRCULATION: II. ROUTING PATTERNS THAT EXACTLY MINIMIZE PATH CROSSINGS

The total number of path crossings between vehicle following different routes on a road network can be taken as a rough proxy for congestion and accident risk. It is therefore useful to identify ways of routing traffic in the plane such that the numbers of crossings are minimized; these can serve as models for the design of traffic management schemes in urban areas. The authors have previously investigated a number of routing patterns; the best ones generated path crossings whose number exceeded a conjectured minimum by 33 percent. In this article, two configurations are put forward that achieve the minimum value. The networks required to support such routing patterns are probably not realizable in practice, but the exercise provides a useful insight into the traffic circulation problem and suggests a yardstick against which other routing patterns can be evaluated.
